6 Claims.

This invention relates to steel studding and more particularly to a construction utilizing rolled channels forboth the floor and ceiling members, as vwell as the studs.

A general object of the invention is to provide a' studconstruction consisting of short rolled channel sections whose intermediate portions may be overlapped, while the opposite end portions are deformed and provided withnotches topermit twisting of the stud into interlocking engagement withsuitable slots in' the floor or ceiling tracks. In that connection, it may be pointed out that the rolled channels constituting the, studs may be overlapped in adjustable relation to vary the effective length of the stud, and held in position byjwiring or equivalent means.

A further object of the'invention is to provide a stud consisting of overlapping rolled sections which ,may be so arranged as to provide a slot therebetween which provides a nailingbase for the attachment of wood or other grounds on either side of thestud, or partition. V

, With the above and other objects in view which will more readily appear as the natureof the invention is better understood, the same consists in the novel construction, combination and arrangementof parts hereinafter more fully described,illustrated and claimed.

Apreferredand practical embodiment of [the invention is shown in the accompanying drawing in which:

Figure 1 isa perspective view illustratingthe invention.

r Figure 2 is a detail side elevation, partly in taken on the line 3- 3 of Figure 2.

Figured is a detail vertical section taken on Similar reference charactersdesignate correponding parts throughout the several figures of thedrawing.

According to the embodiment shownin Figure 1, the invention includes .in itsorganization a floor attaching member or track A and a'ceiling attaching member or track B. These elements A and B are preferably rolled channels and are intended to have the edges of their flange portions respectively engage the floor and the ceiling while the Webs thereof face each other. As will be observed from Figure 1, the said webs are provided with the fastening receiving openings and with the stud receiving and interlockingslots 2.

The stud is designated generally as C and preferably comprises the short rolled channel sec.- tions 3-3. The inner ends of said channel sections 3-3 may be overlapped in nesting relation and are, therefore, slidably related to vary the effective length of. the stud. Any suitable means such as the wire 4 may be used for holding the channel sections in the selected adjusted position. The outer ends of the channel sections 3-3 are preferably deformed into substantially tubular formation as indicated at 5. That is to say, 10 the flanges of the channels 3 are bent inwardly toward each other, so that the effective depth or thickness of each end 5 of the channel is less than the width. of the slots 2 in the track members A and B. Inwardly of the end of each channel section 3 suitable notches 6 are provided. These notches do not completely pierce the inwardly bent or deformedfianges constituting the portions 5 for the purpose of giving strength to the end of the channelsection. The notches 6 arepreferably of such a depth that the bottoms thereof are'of substantially the width of the slots 2 in the track members as will be apparent from Figure 4.

With the deformed and notched formation of the. channels 3, it Will be apparent that the smallest diameter thereof may be inserted in the slots 2 of the track members, so that the notches 66 lie opposite the abutment edges of the slots 2 in the track members. Then, by twisting the chan 3 nel on its longitudinal axis, the notches may be made to receive the edges of the Web of the track adjacent the slot to thus frictionally interlock the stud with the channel.

The foregoing features of, construction de- '35 scribed in connection with Figure 1 also apply to Figures 2 and 3." However, in these figures,

there is the difference that the channel members 3 constituting the stud C are arranged back to back, so as to provide a space or slot 1 be- "40 tween the members which will serve as a nailing ground. Any suitable and .convenientmeans may be utilized for holding-the channel sections 3 in back to back relation, that is, so that the webs thereof face each other insufficiently spaced rel'ation to provide the fastening receiving slotl. According to the example shown in Figure 2, one of the channelsections 3 is provided with suitable loops 8, welded or otherwise secured to the back of one of the channel sections and into 5 which the other channel section may be slidably inserted. It will, of course, be understood that in this form of the invention, the channel sections may be adjusted longitudinally, one with relation to the other, and that the spacing of the loops or equivalent members 8 may be varied as specifications require. In other words, it is within the scope of the invention to assemble the channel sections 3 in any suitable manner which will provide a slot for serving as a nailing ground. For example, the overlapped portions of the sections 3 may be Welded together at suitable spaced points with suflicient space left between the webs of the sections to provide a nailing slot.

In erecting a stud system in accordance with the present invention, the track elements would be first attached to the floor and ceiling, and then the ends 5 of the channel sections would be inserted in the slots 2 and twisted into interlocking relation with the track elements. According to Figure 1, it will be apparent that one channel section may be first twisted into interlocking engagement with the desired track element and then the other section may be likewise fitted to its related track section. The two sections may be then connected by wiring or other suitable means. In connection with the form shown in Figure 2, it will, of course, be understood that the over lapped portions of the channels 3 may be located 'at the bottom of the stud or the top of the stud, depending upon-where the nailing ground is desired. In other words, the construction shown in Figure 2 may be inverted. After the stud has been applied to the tracks, metal lath or other plaster base may then be applied to the sides of the stud in the usual manner. Wood or steel grounds may then be secured at the desired locations. It may also be pointed out that the stud, if inverted from the position shown in Figure 2 may then have its lower end fitted into a combined nailing ground and holding shoe of the type shown in my co-pending case, Serial #277,291 filed June 3, 1939, which is adapted to fit in a hollow partition track secured to the floor.

From the foregoing, it is believed that the present invention provides a simple, practical and accurate construction for erecting channel iron partitions, particularly solid partitions.

I claim:

7 l. A stud construction for partitions and the like, including, floor and ceiling channel tracks arranged to have the edge portions of their flanges engage the floor or ceiling respectively and their webs facing each other, said webs being slotted to provide opposite stud engaging abutments, and a pair of channel elements constituting the stud, the outer ends of each channel element being formed so as to be of less width in one direction than the distance between the edges of the slots in the floor and ceiling channels and provided inwardly of said ends with a pair of transverse notches whereby the said outer ends of said stud channel elements may be twisted into interlocking engagement with the abutments formed by the slot of a related track, and means for connecting the overlapping portions of the channel elements.

2. A stud construction for solidpartitions and the like, including, rolled floor and ceiling channel tracks arranged to have theedge portions of their flanges engage the floor or ceiling respectively and to have their webs facing each other, said webs being slotted to provide opposite stud engaging abutments, and a. pair of rolled channel elements constituting the stud, and adjustably related to vary the effective length of the stud formed thereby, the outer ends of each channel element being provided with a pair of transversely disposed closed notches whereby said outer end of each channel stud element may be twisted into interlocking engagement with the abutments formed by the slots in the floor and ceiling channels, and means for connecting the overlapping portions of the channels forming the stud.
